Configuring sipdroid to use SMSDiscount is a lot easier than most tutorials on the internet show. There is no need to create any pbxes.org account or anything else.
Just download the latest version of sipdroid and go to the sipdroid settings screen:
In one of the SIP accounts (in my phone I used the first one) use the following settings:
- Authorization Username: your username on SMSDiscount
- Password: your SMSDiscount password
- Server or Proxy: sip.smsdiscount.com
Leave all other settings as they are and your are good to go!
If this does not work for you, please inform me.
